IPC: G03F7/30
Filed: 1980-12-26
Abstract: PURPOSE:To prevent the formation of an unnecessary mustache parttern by gradually decreasing a developing solution with the lapse of time while increasing a rinsing liquid which shrinks the irradiated section of beams by degrees when developing negative type photosensitive resin. CONSTITUTION:Only the developing solution is supplied until a fixed time t1 passes after commencing development, and sections 2a not exposed are eluated. The rinsing liquid is fed little by little after the time t1 when the swelling of sections not exposed 2b does not advance sufficiently while the supply of the develping solution is gradually decreased. Accordingly, swelling by the developing solution is inhibited, adjacent exposed sections 2b is kept contact, and the formation of the mustache patterns 4 is prevented. Only the rinsing liquid is supplied after time t2, and residue is removed completely. It is preferable that a rubber group resist is used as the negative type photosensitive resin film 2, while a material, the principal ingredients thereof are petroleum group hydrocarbon and xylene, is used as the developing solution and a material, the principal ingredicent thereof is butyl acetate, is used as the rinsing liquid.

Title: Method of molding synthetic resin with high accuracy
Inventor: KATSUMURA NOBUO
IPC: B29C61/00
Filed: 1982-10-27
Abstract: PURPOSE:To manufacture moldings of high planar accuracy with the low cost, which are useful for optical parts such as mirrors and lenses and have a shape faithfully profiling the shape of molds, by a method wherein resin is injected into the molds and molding is then performed while pressurizing the resin with movable parts of the molds. CONSTITUTION:Molds D1, D2 are held integral by a mold fastening force P and then heated up to injection temperatures. A given amount of resin is poured into a cavity C from an injection cylinder A. Next, a pressurizing piston Po is advanced to close a gate B, and the molds are heated to melt the injected resin and then cooled. At this time, pressurizing of the piston Po imparts pressure Pc against a movable core E of the mold to transmit a pressure to the cavity C. When the resin is hardened under continuous pressurizing in this way, the movable core E serves to reduce the volume of the cavity C attendant on volume reduction resulted from hardening, thus making it possible to manufacture moldings without sink mark.
